采用水溶液法结合热处理法制备了尺寸均匀的Zn-Sn-O多孔纳米立方体。在ZnSn(OH)6固体纳米立方体的制备过程中,通过调节煅烧温度,可以很容易地调节Zn-Sn-O纳米立方体的化学组成、形貌和微观结构,这对储锂性能有重要影响。进一步的研究表明,在600 °C下制备的多孔Zn-Sn-O纳米立方体表现出良好的倍率性能,在200 mA g-1的电流密度下,50次循环后的可逆容量为700 mAh g-1,这可能是锂离子电池负极材料的巨大潜力。
Porous Zn–Sn–O nanocubes with a uniform size were synthesized through a facile aqueous solution route combined with subsequent thermal treatment. The chemical composition, morphology, and microstructure of Zn–Sn–O nanocubes, which have significant effects on the lithium storage performances, were easily tuned by adjusting the calcination temperature in preparation processes of ZnSn(OH)6 solid nanocubes. Further studies revealed that porous Zn–Sn–O nanocubes prepared at 600 °C exhibited a good rate capability and a high reversible capacity of 700 mAh g−1 at a current density of 200 mA g−1 after 50 cycles, which may be a great potential as anode materials in Lithium-ion batteries.
